IMPROVEMENT IN SEED-DROPPERS.

Speciiication forming part of Letters latent No. 173,545, dated February/A15, 1876 application tiled i l October 23, 1875.

To all whom 'it may concern e Be it known that I, HERMANN H. KOELLER, of Camp Point, in the county of Adams and State of Illinois, have invented a new and useful Improvement `in Seed-Droppers, of which the following is a specification Figure l is a top view of my improved device. Fig. 2 is a vertical longitudinal section seed than enough to ll the dropping-holes ot' said slide, and which shall be simple in construction, and not liable to get out of order.

The invention consists in combining a ccntrally-pivoted two-armed spring with a cutoff block, and in making the cut-oli' of aside slotted box, a block with side pins, a spring, abolt, and certain angle-plates, as more particularly hereinafter described.

A represents a portion of the frame-work of a seed-planter.

B is the base-frame of the seed-hopper, the side bars of which project below the end bars, and are securely bolted to the frame A. To the lower side ot' the middle parts o f the side bars of the base'frame B is secured a plate, C, which has a hole formed through its center, through which the seed passes to the ground.

Upon Vthe platevO, and between the side bars of the frame B, is placed the dropping-slide D, which may be operated by any of the wellknown means, and through which are formed two transverse rowso'f two or more holes, d. The holes d are graduated in size, as shown in Figs. 1 and 3, so that the larger or smaller holes may be used, according as larger or smaller seeds are to be planted, or more orless seed is to be dropped for a hill. E is the hopper,in the bottom of which is formed a slot, e, to allow the seed to pass into the droppingholes d of the slide D. l

Upon the lower part ofthe ends of the hopper E are formed'anges F, which may be the projecting ends ofthe bottom of said hopper E.

larger or smaller set of holes, d', in the drop pingslide D, according as the size' or quantity of seed to be dropped may require.

H is the cut-off box, in the sides of which are formed short 'slots to receive pins formed upon the sides of the cut-off block I, which is placed in the cavity of the box H, and the middle part of which is concaved, as shown in Fig. 2.

The upper sides of the end parts of the block I are grooved to receive the arms of the Wire spring J, the middle part of which is coiled around a bolt, K, which passes through the box H, and secures the angle-plates L to the sides of the said box.

The lower parts of the angle-plates L, are bolted to the bottom of the hopper E. The plates L secure the cutoff in place, and at the same time cover up and protect the slots in the sides ofthe box H.

By this construction, as the seed is carried in at either end of the cut-oft' by the slide D, the end of the block I will rise, while the spring J will press the other end of the block I down more Irrnly, so that it will act as a perfect cut-oft', and at the same time will not crush or injure the seed.

Having thus described my invention,

yclaim asnew and desire to secure by Letters Patentl. The combination, with covered cut-off block I, constructed Vas described, of the twoarmed spring J ,centrally .pivoted at K, as

shown and described, whereby the pressure on one side is increased whenever the other side is forced upward.

2. A cut-oli` to be used in connection with hopper and slides, consistingpof a side-slotted box, H,block I, having side pins, a spring, J, a bolt,K, and angle-plates L, all arranged as shown and described.
